| Zusammenfassung: | Copyright © 2017 Elsevier Masson SAS. All rights reserved. Hydrogen sulfide (H2S) is a gaseous signaling molecule that mediates physiological processes in animals and plants. In this study, we investigated the relationship of H2S and mitogen activated protein kinase (MAPK) under cold stress in Arabidopsis. H2S up-regulated MAPK expression levels and was involved in the cold stress-related upregulation of MAPK genes expression. We then chose MPK4 whose expression level was influenced the most by H2S as a target and found that H2S's ability to alleviate cold stress required MPK4. Both H2S and MPK4 regulated the expression levels of the cold response genes inducer of CBF expression 1 (ICE1), C-repeat-binding factors (CBF3), cold responsive 15A (COR15A) and cold responsive 15B (COR15B). H2S inhibited the opening of stomata under cold stress, which required the participation of MPK4. In conclusion, MPK4 is a downstream component of H2S-related cold-stress resistance, and H2S and MPK4 both regulated the cold response genes and stomatal movement to response the cold stress |
